ABSTRACT:
A photocurable composition which can be produced and cured while utilizing two different polymerization modes, can be used for bonding over a sufficiently long time period, and has excellent peel strength.The composition comprises (A) a compound containing a polymerizable unsaturated bond and giving a homopolymer having a glass transition temperature of 0 to 100° C., (B) a compound which has an unsaturated bond and is copolymerizable with the compound (A), (C) a compound having at least one cationically polymerizable group per molecule, (D) a polymerization catalyst which upon irradiation with light initiates the polymerization of the compounds (A) and (B), and (E) a cationic polymerization catalyst which upon irradiation with light initiates the cationic polymerization of the compound (C) at the cationically polymerizable group(s).
